Description
Zoom on the Ryobi RY905500
In summary, the Ryobi RY905500 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to ensure that a power failure will not prevent them from working
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Ryobi RY905500
The Ryobi RY905500 is powered by a 420 cc Ryobi OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 5500W as well as a peak wattage of 6875W.
Enjoying a noise rating of 78 dBA (less noisy than a vacuum cleaner), this generator gets running thanks to Ryobi's EasyStart pull-start mechanism (more information below).
With a fuel capacity of 6 gallons, the RY905500 may run for around 10 hours at 50% load with a full tank (fuel consumption around 0.6 GPH).
The powering of sensitive electronic devices with the RY905500 is not recommended due to its relatively high THD (<20%).
Outlets
The control panel features the upcoming 5 AC outlets:
Since the RY905500 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
Portability
The design of the Ryobi RY905500 is a typical, open frame, with the dimensions of L31.5 x W29 x H24 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 192 pounds. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.
EasyStart Mechanism
Ryobi's 3-step EasyStart mechanism
The unit benefits from Ryobi’s EasyStart mechanism. This 3-step starting system allows you to easily start your generator. It works in the following way:
- Put the engine switch on the “ON” position, and place the lever on the “START” position
- Pull the recoil until the engine runs
- Let the engine run 15 to 30 seconds and place the lever on the “RUN” position
Features
The RY905500's control panel
The RY905500's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Ryobi RY905500's package also includes these accessories: oil and tool kit.
Emissions
The Ryobi RY905500 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, which makes it suitable for use in forested areas.
Product Video
The Ryobi RY905500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY905500 compare to generators of similar power (between 5000 and 6000 W).
- With its weight of 192 lbs, the Ryobi RY905500 is one of the heavier generators in the 5000-6000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN GN6000, with a dry weight of only 119 lbs.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 78 dBA can be considered somewhat noisy. If noise emissions are one of your priorities, you may be interested in the Honda EU7000iS, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- Regarding its autonomy, the autonomy of the RY905500, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Cat RP5500, boasting with around 15 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. As this generator uses an estimated 0.6 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the A-iPower SUA7000L, with a fuel consumption of 0.36 GPH could be in your good books.
The bottom line
- Several accessories included
- GFCI Outlets
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
- On the heavy side (192 lbs)
- On the noisy side (78 dBA)
- Relatively low run time
